Wireless printer loses signal from Netgear gateway

Canon MG 8120 wireless printer loses signal from new Netgear B90 7550 router. The signal is sporadic. Sometimes O.K., sometimes have to set up again, and sometimes printing will start several minutes later. I used the push buton WPS security set up after entering the SSID and security key. It was an easy set up. I didn't use the PIN code set up because I didn't know what the printer PIN code was or where to find it. My laptop upstairs has a good steady signal. Just the printer (4 feet away) is the problem. Do I have the proper security settings in the printer?

Thanks in advance for responding. Let me know if I'm in the wrong forum here.

Thanks G41M. There are no cordless phones in the room. But, just now my wife was trying to print from the laptop upstairs and the printer in question would not print. I powered down the printer and right back up, and it printed very quickly. Apparently something is confusing the printer. I'll run thru the security settings in the printer again and see what I can come up with.

I went into "device user settings", "read/write attributes" on the Canon MG 8120 printer and chose "writable from LAN PC", then O.K.'d "can not access memory card from USB connected PC". I've had no more sporadic signal losses.

I need to re-open this subject. I thought it was solved, but I have to power the printer down quite freqeuently after it goes to sleep to get it to print wirelessly. It is only 4 feet from the desktoop PC and the Netgear router. It works fine except for the "going to sleep and not waking up thing". I print from upstairs on a lasptop and from my workshop desktop PC with no problems s long as thne signal is not lost asfter it sleeps. a quick power down and up
(about 20 seckl) always gets it to receive the previous print signal.

Normally, printers go to sleep to conserve energy (eco-friendly) and should wake up if a print request is received but your printer looks somewhat in "deep slumber" which is really odd. Try to go Canon site and see if there Is an update for your printer model firmware and update it. If your firmware is up-to-date, you can try pinging the (ip address) printer and hope it wakes up before printing. This will save you time and energy going downstairs to physically wake the printer. Or, if there is setup to disable sleep mode in the printer, disable it.

No means of completely disabling the sleep mode. Could not find the IP address of printer. Where should I look? It's not in any of the info on the printer itself, settings, LAN settings, etc. I did install the latest firmware, but it still appears to be sleeping through it's wake up call.

From the manual. To check the IP address of the machine, use the up/down arrow head button to display Setup on the HOME screen and touch the right FUNCTION button, then using the arrow head and OK buttons, select Device settings > LAN settings > Confirm LAN settings > WLAN setting list or LAN setting list to check IP address.

Thanks. Never could see it, but had an option to print all LAN info. I'll send the IP address next time it doesn't "wake up". This (doesn't wake up and print)only happens when it has been inactive long enough to sleep, and doesn't happen every time under those conditions.

Tried pinging the printer IP address, and nothing happened. The only way I've got it to wale up thus far is to give it a quick power down and up. The printer signal shows strong on all three of my computers. One is all the way accross the house in a shop. Let me do a little more work on this tod determine if it's related to the print from a particular computer.
